25mm x 5mm x 2mm (1" x 3/16" x 5/64") Neodymium Block Magnet – N52 Grade 

Key Features:

• Dimensions: 25mm Length × 5mm Width × 2mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 4.4 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for a professional finish
• Magnetization: Axially magnetized through the 2mm thickness (Poles on the large 25x5mm faces)
• Shape: Rectangular Power Strip

Material Description:

Our 25x5x2mm N52 blocks are built for professional engineering and high-load DIY projects. The 2mm thickness provides the volume necessary to generate a deep magnetic field, allowing it to "reach" through several millimeters of non-magnetic material. The 1-inch length ensures the magnet resists rotation and provides a massive surface area for adhesive bonding in woodworking, robotics, or industrial assemblies.

Handling Advice: At over 5 lbs of pull force, these magnets are powerful. They will jump toward each other from a significant distance. Always handle one at a time and separate them by sliding the top magnet off the stack horizontally to avoid chipping the brittle neodymium core or causing painful skin pinches.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause painful skin pinches or blood blisters. Handle with caution.
• Choking Hazard: Small size is dangerous for children and pets. Keep strictly in a secure container.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.
• Electronics: Safe for most modern devices at a distance, but avoid direct contact with hard drives and magnetic strips.

Applications:

• Heavy-duty magnetic latches for cabinetry, secret panels, and hidden doors
• Industrial proximity sensors and robust magnetic triggers
• High-torque couplings for custom robotics and RC projects
• Modular mounting systems for lightweight tools and workshop organization
• Invisible edge-mounting for large-scale graphics and signage
